| ABSTRACT Aiming at the generation of new guava varieties with superior attributes, we conducted this study adopting the REML/BLUP procedure at individual level. Seventeen segregating guava families were evaluated in a randomized-block design with two replicates and 12 plants per plot. Families were obtained after controlled biparental pollination. The studied individuals showed high genotypic variance for fruit weight (FW), total yield (YLD), and ascorbic acid content (AAC). The heritability coefficients of the mean of progenies led to high progeny-selection accuracy for pulp yield (PY), soluble solids content (SSC), in addition to FW, YLD, and AAC; moderate accuracy for fruit acidity (FA) and SSC/FA ratio; and low accuracy for mesocarp thickness (MT) and... |

| Eight morpho-agronomic traits have been measured in six common bean (Phaseolus vulgaris L.) cultivars and their 15 hybrids aiming to estimate parents potential per se and heterotic effects of hybrid combinations (Gardner and Ebehart's method, 1966). Enough variability has bees detected among the parents for most of the studied characters. Excepting first pod insertion height the results have shown a great deal of complementation for the scored traits. Hybrids LPSPI 93-17 x FT Nobre and LPSPI 93-19 x FT Nobre have revealed the highest chances of selecting for earlier plant emergence and flowering cycle; on the other hand, 'LPSPI 93-17', 'Ápore', 'Rudá' and 'Campeão-1' have presented high potentials per se, as well as in hybrid combinations, for grain... |
